To all whom t may concer/n.:

Be it known that I, GRANT W. ROLLINS, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Axle Packings, of which I declare the following specification to be a full, clear, and exact description.

This invention relates to an improved axle packing.

The principal object of this invention is to provide an improved arrangement for the axle packing in the live axle of a motor vehicle *which will lengthen the life of the packin and prevent its wearing unduly.

Furt er objects, and objects relating to Aeconomies of manufacture and details of construction, will denitely appear from the detailed description to follow.

I accomplish the .objects of my invention by theA devices and means described in the following specification. My invention is clearly defined and pointed out in the appended claims. Q A Structure constituting a preferred embodiment of my invention is .illustrated in the .accompanying drawing, forming a part of this specication, in which- Figure I is a part longitudinal, sectional view through the end .of a live axle embodying my invention.

Figure II is a sectional view through the elements going to make up m .improved arrangement of axle' packing, t e elements being shown separated in order to make their construction more clear.

Figure III -is a fragmentary, top plan view of the lock nut'secured to the end 'of the axle casing, andV Figure'IV 1s a-plan view of the retainying ring carried by the lock nut on the axle casing and which carries the packing elements.

In the drawings, similar reference nu- `merals refer to similar parts throughout the several views. i

Considering the drawing, I have shown a stationary axle casing 11 in which the axle shaft 10 is .rotatably mounted. The hub 14 is keyed to the outer end of shaft 10 by means of a spline 15 and the hub box 12 having a spoke flange 13is secured to the flange o the hub 14 by means. of boltsl (not shown) the holes for onefof which are shown' in the -anges ,elements whichl comprise the inner Ypackinlg wit numbered parts of the.

13 and 14 at 13 and 14 respectively. The lock nuts 24 and 28 are threaded .on to the end of the axle casing 11 and are/provided with notches 25 in the periphery thereof, a lock washer 26 beingdisp-osed between the nuts 24 and 28 and provided with the tongues 27 which are bent alternately in opposite directions so as toengage in the notches 25 in said nuts 24 and 28 to prevent the rotation of said nuts relative to each other.

A retaining ring 21 is provided, having tongues 23, whichare disposed in certain of the notches 25 formed in the nut 24. The retaining ring 21 is also provided with 70 radially extendin tongues 22 as clearly shown in Figure of the drawing.

This retaining ring 2 1 carries the packing ring 20 andthe outer packing ring18 75 the washer 19 disposed between the two. rings. A washer 16 is provided which abuts the inner surface of the hub 14 and is pro-v vided with an inwardly bent flange 17 as is clearly shown in Figure II of the drawing. The bearing 29 is disposed between the hub box 12 and the axle casing 11 and retained in place by the stationary sleeve 31 of the brake hub. The ring 3() is screwed into the interior of the hub box 12 and secures in place the packing 32 in the usual manner.

From the description of the parts 'ven above, the operation of my device shou d be very readily understood. It is customary to provide a packingring which lis disposed around `the shaft and between the innerv surfacegof the hub 14 and the end of the axle casing 11. Where such a packing ring is provided, due to the fact that the hub rotates relatively to the axle casing, lthe side of the packing ring will become worn due to the friction caused by its rubbing against adjacent surfaces. As I have already pointed out, the principal object4 of my invention is held stationary because the retaining ring 'fing having a series of'lateral 1.
